Each fireproof sealing hole 21 is coaxially corresponding to the wall-penetrating hole, and the diameter of each fireproof sealing hole 21 is greater than or equal to the outer diameter of the corresponding optical cable; and multiple adaptive sealing rings 3, each of which... The self-adaptive sealing ring 3 is embedded in each of the fireproof sealing holes 21 and can be gradually disassembled from the inside to the outside to adapt to the outer diameter of the optical cable; a fixing strip 4 is placed on the topmost fireproof sealing module 2, and the fixing strip 4 and multiple fireproof sealing modules 2 penetrate vertically to form at least two fastening holes 6, and the fastening holes 6 do not interfere with the fireproof sealing holes 21; and at least two bolt groups 5, each bolt group 5 is adapted to each of the fastening holes 6 so that the fixing strip 4 presses the multiple fireproof sealing modules 2.

[0027] like Figure 1 , 2 As shown in Figures 3 and 6, there are two fastening holes 6, which are used to fix the fireproof sealing module 2, thereby tightening and fixing the optical cable and improving the sealing performance of the fireproof sealing module 2.

[0028] The wall penetration sealing device includes a fireproof frame 1 fixed to the wall, with a wall penetration opening in the wall. Multiple fireproof sealing modules 2 are installed within the fireproof frame 1, forming multiple fireproof sealing holes 21 between the fireproof modules 2. The fireproof sealing holes 21 are coaxially aligned with the wall penetration opening. Each fireproof sealing hole 21 is filled with a gradually removable self-adaptive sealing ring 3. When optical cables of different outer diameters pass through, a portion of the self-adaptive sealing ring 3 can be removed to adapt to the outer diameter of the optical cable. A fixing strip 4 is installed on the topmost fireproof sealing module 2, and at least two vertically penetrating fastening holes 6 pass through the fixing strip 4 and the multiple fireproof modules 2. The fastening holes 6 do not interfere with the fireproof holes 21 and are secured by at least two corresponding bolt sets. 5. The fixing strip 4 presses the multiple fireproof sealing modules 2 together. Compared with traditional sealing methods such as using baffles and openings, the present invention can adapt to optical cables of different outer diameters through the gradually removable adaptive sealing ring 3. It has high versatility and can be used to seal holes of laid cables and various wire diameters. The hole diameter is easy to control. Compared with traditional sealing methods such as fireproof putty and fireproof bags, it is not easy to crack and has better anti-blocking and sealing performance. It meets fire protection requirements and also meets rodent prevention requirements. In addition, the gradually removable adaptive sealing ring 3 can protect the outer insulation layer of the optical cable and can also be used for optical cables of different outer diameters, improving the quality of optical cable laying, reducing rework costs, improving the efficiency and quality of on-site installation, and saving a lot of time.

[0029] like Figure 2 As shown, the fireproof frame 1 includes: a hollow frame 11 with multiple fixing holes 111 (specifically four holes) for bolt-fixed connection to the wall; the interior of the hollow frame 11 is used to install multiple fireproof sealing modules 2; two right-angle steel profiles 12 are respectively located on the same side of two opposite edges of the hollow frame 11, each right-angle steel profile 12 forming a mounting groove 14 with the fireproof frame 1 for installing the multiple fireproof sealing modules 2; and a base 13 located at the bottom of the hollow frame 11, with both sides of the base 13 extending to connect with the cross-sections of the two right-angle steel profiles 12, and the base 13 supporting the multiple fireproof sealing modules 2. Furthermore, the hollow frame 11, the two right-angle steel profiles 12, and the base 13 are an integral structure.

[0030] Please continue to refer to this. Figures 2-3As shown, the fireproof frame 1 is an integrated frame, with an internal mounting groove 14 for fixing the fireproof sealing module 2. The mounting groove 14 has a top opening and is surrounded by a hollow frame 11, right-angle steel profiles 12 on both sides, and a base 13. By fastening the bolt group 5 into the fastening holes 6 that pass through the fixing strip 4 and the fireproof sealing module 2, the fireproof sealing module 2 is pressed into the mounting groove 14 inside the fireproof frame 1, thereby further improving the sealing performance of the wall hole sealing device and enhancing its fire resistance. Specifically, the bolt group 5 includes a fixing bolt 51 and a fixing nut. The fixing bolt 51 is inserted into the fastening hole 6 and tightened with the fixing nut.

[0031] Among them, such as Figure 4-6 As shown, the fireproof sealing module 2 is made of fireproof bakelite material. Fireproof bakelite, chemically known as phenolic resin, was the first plastic to be industrially produced. It possesses high mechanical strength, good insulation, heat resistance, and corrosion resistance, making it commonly used in the manufacture of electrical materials such as switches, lamp holders, earphones, telephone housings, and instrument housings. The name "bakelite" derives from this. Its invention was of great significance to industrial development. Fireproof bakelite is characterized by its non-absorbency, non-conductivity, high temperature resistance, and high strength. Because it is widely used in electrical appliances, the fireproof sealing module 2 is made by mixing powdered phenolic resin with sawdust, asbestos, or clay, and then pressing the mixture into a finished product using a mold at high temperatures. Phenolic resin was the world's first artificially synthesized resin. Fire-resistant bakelite possesses properties such as insulation, static electricity resistance, wear resistance, and high-temperature resistance, making it suitable for use in electronic products such as insulated switches and variable resistors, as well as in mechanical molds and production line fixtures. It is applicable to motors, electrical equipment, and insulating structural components with high mechanical performance requirements. With good mechanical strength, it is primarily used in the processing of insulating components in ICT and ITE fixtures and is widely used in electrical products.

[0032] Therefore, this embodiment adopts an assembled fireproof sealing module 2, made of fireproof bakelite. Each fireproof sealing module 2 is divided into upper and lower parts, each part consisting of fireproof bakelite and an adaptive sealing ring 3, as shown below. Figure 4 and Figure 5 As shown, at least two fireproof sealing holes 21 have different inner diameters. Fireproof sealing holes 21 and adaptive sealing rings 3 of different sizes are set according to the diameter of the optical cable passing through the sealing port. The adaptive sealing rings 3 are made by peeling off excess adhesive strips layer by layer according to the outer diameter of the optical cable until they match the outer diameter of the optical cable.

[0033] Furthermore, such as Figure 4As shown, one of the fireproof sealing modules 2 has a semi-circular fireproof sealing hole 21 on its upper edge, and the corresponding lower edge of the upper fireproof sealing module 2 has a semi-circular fireproof sealing hole 21, forming a semi-circular fireproof sealing hole 21; or, one of the fireproof sealing modules 2 has a semi-circular fireproof sealing hole 21 on its lower edge, and the corresponding upper edge of the lower fireproof sealing module 2 has a semi-circular fireproof sealing hole 21, forming a semi-circular fireproof sealing hole 21. That is, from bottom to top, starting from the bottommost fireproof sealing module 2, two fireproof sealing modules 2 form a group, forming a number of spaced fireproof sealing holes 21 for inserting a tearable self-adaptive sealing ring 3 and matching optical cables of different outer diameters, thereby adapting to optical cables of different sizes and meeting sealing performance requirements, satisfying both fireproof and rodent-proof requirements.

[0034] Among them, such as Figure 1 , 4 As shown in Figure 5, the adaptive sealing ring 3 comprises two semi-cylindrical sealing strips. Each semi-cylindrical sealing strip includes a semi-circular ring-shaped sealing strip arranged layer by layer from the center outwards to be inserted into the fireproof sealing hole 21. Each semi-cylindrical sealing strip is peeled layer by layer from the center outwards to match the outer diameter of the optical cable. Furthermore, the adaptive sealing ring 3 is made of a tearable rubber elastomer material, which is easy to peel and elastic, allowing it to fill each fireproof sealing hole 21 while being peeled, thus satisfying the sealing performance. This embodiment, through the assembled fireproof sealing module 2 and the adaptive sealing ring 3, reduces the bending loss of the optical cable during fixing, avoiding damage to the optical cable when passing through wall holes.

[0035] In this embodiment, the optical cables are arranged sequentially from the bottom layer through the adaptive sealing rings 3 inside the fireproof sealing holes 21. The wire clamps of the fireproof sealing module 2 are then placed into the fireproof frame 1, and the optical cables are pressed firmly. This device is suitable for sealing in various scenarios, especially for sealing existing holes where some cables have already been laid. Based on the cable diameter, a suitable adaptive fireproof ring is selected and pressed in layer by layer.

[0036] Among them, such as Figure 1 and Figure 2 As shown, the fixing strip 4 is fixed by bolt group 5 and is detachable. After removal, the overall fireproof frame 1 has a U-shaped structure, which can be installed after the optical cable is laid. This design can avoid damage to the optical cable and also improve the applicability of the device. It does not need to be installed before the optical cable is laid. By fixing the strip 4, the sealing performance is improved, the applicability of the sealing module is improved, and the installation efficiency and quality are improved, saving a lot of time and reducing rework costs.

[0037] The above description provides a detailed account of the embodiments of this utility model, but the content is merely a preferred embodiment and should not be construed as limiting the scope of this utility model. All equivalent variations and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
